IUBMB Enzyme Nomenclature


Accepted name: lipopolysaccharide-transporting ATPase

Reaction: ATP + H2O + lipopolysaccharidein = ADP + phosphate + lipopolysaccharideout

Systematic name: ATP phosphohydrolase (lipopolysaccharide-exporting)

Comments: ABC-type (ATP-binding cassette-type) ATPase, characterised by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. Enzymes of Gram-negative bacteria that export lipo-oligosaccharides and lipopolysaccharides.
